84 Setting Up the Dell™ DR Series System as a CIFS or VTL Backup Target on CommVault Simpana |
April 2015
5 Monitoring deduplication, compression, and
performance
After backup jobs have run, the DR Series system tracks capacity, storage savings, and
throughput on the DR Series system dashboard. This information is valuable in
understanding the benefits of the DR Series system.
Note: Deduplication ratios increase over time. It is not uncommon to see a 2-4x
reduction (25-50% total savings) on the initial backup. As additional full backup jobs are
completed, the ratios will increase. Backup jobs with a 12-week retention will average a
15x ratio, in most cases.
